    Hello again,

    you will love to hear that you can drop the above statement completely. After
    digging deeper into the case I found out that it was caused by a dead switch.
    So this is no -pre4 problem, but a hardware issue. The switch corrupted about
    every 20th packet.
    So I can tell nothing negative so far about -pre4 with 4 GB.
    I'll try with 6 GB now.

    Regards,
    Stephan
